You don't buy a stock in an exploration company who have given a legitimate timeline for drilling in a new area with the potential to make the stock a 3 or 4 bagger, then drop your shares LAST MINUTE before the company even announces anything (and all prior announcements have been confident).

That makes you wonder why they even bought in the first place? Or if it's a nobody like me selling them, a crafty investor playing tricks; or people know something that hasn't been announced. (which would be strictly against Listing Rule 3.1.)
